The enzymatic profile of urine and plasma in bovine urinary bladder cancer (enzootic bovine haematuria).

The enzymatic profile of urine and plasma in field cases of bovine bladder cancer was studied. Urinary lactate dehydrogenase activity was significantly altered along with the isoenzyme pattern. Activity of alkaline phosphatase and beta-glucuronidase was decreased in the affected animals. No significant changes were observed in acid phosphatase, or arylsulphatase A and B activity. In plasma, lactate dehydrogenase activity was elevated without any change in the isoenzyme pattern. No significant changes were observed in the other plasma enzymes studied or in the sialic acid concentration.
